BAG-CLEANING- MACHINE.

oasme.

To all whom it may concern:

Be it known that I, NORMAN E. GARDNER, a citizen of the United States,residing at Easton, in the county of Northampton and State ofPennsylvania, have invented a new and useful Bag-Cleaning Machine, ofwhich the following is a specification.

This invention relates to bag cleaning machines.

The object of the invention is to provide a machine of this characterwhich shall be simple in construction, and thoroughly efficient in arapid and expeditious manner to remove dust or dirt from fabric bagswhereby to prepare them for reuse.

With the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction and combination of parts of a bag cleaning machine, as willbe hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which like characters of reference indicate corresponding parts:Figure l is a view in side elevation, partly in section of a bagcleaning machine constructed in accordance with the present invention.Fig. 2 is a front elevation, partly in section, of the machine.

The device embodies a drum supported to rotate upon a frame or basedesignated generally 1. The drum is constructed, in part, of two spiders3 and 4, each of which has an outwardly extending tubular hub 5 that ismounted in suitable journal boxes 6 carried by the frame 1. To the armsof each of the spiders are secured two concentrically disposed rings 7and 8, the former being located at the extremities of the spider armsand the latter at any point adjacent to its center. Secured to the innersioles of the spiders and rings is wire netting 9 which, as will beobvious, is employed for the purpose of permitting ready escape of thedust removed from the bags. In order to provide a plurality of pocketsfor the insertion and removal of the bags, the screen is cut away atspaced intervals in its periphery, the material removed being V- shaped,and the edges of the pocket members 10 thus provided are reinforced byme tallic bars 11 and 12 which are riveted to the rings 7 and 8 whilethe inner ends of the pockets open radially toward the axis andcommunicate with the interior of the drum. The mouth of each pocket atits Specification of Letters Patent.

outer end is closed by a door 13 that is secured by hinges 14 to thebars 11, and is held closed by a suitable catch or latch 15. As will benoted by reference to Fig. 2, the periphery of the drum is also screenedexcept over said doors 13 so that dust removed from the bags will becertain to escape.

Extending loosely through the hubs 5 of the spiders is a shaft 16 towhich is secured a winged beater 17 of any preferred construction, andmade of any material best suited to the purpose. Motion is imparted tothe shaft 16 and thence to the beater by a gear 18 fast on one of thehubs that meshes with a pinion 19 on a shaft 20, upon which is alsokeyed a gear 21 that meshes with a pinion 22 on the shaft 16, and bythis arrangement it will be seen that the beater is rotated in the samedirection as the drum but at a higher rate of speed.-

In the operation of the machine the doors 13 of the various pockets areopened and the dust laden bags fed into the cylinder. As the latterrevolves the pockets pick up the bags at the bottom and carry themupward on the ascending side of the drum and drop them upon the heaterswhich toss them about within the drum and forward in the direction ofrotation and operate to dislodge the dust, or loosen any adheringmatter, such as cement, and this will escape through the sides and endsof the cylinder. At the conclusion of the operation, the doors of thevarious pockets are opened and the bags removed. These movements ofparts carry the bags slowly up the ascending side of the drum within thepockets, and when any one of the latter has reached a point suflicientlyhigh to dislodge its contents the bags therein fall out and droa ontothe more rapidly moving beater. If they fall onto the ascending side ofthe beater they are simply tossed, but if the drum is moving rapidlyenough to cause the bags to fall onto the beater at a point beyond itsexact top they are both tossed and thrown forward and therefore insteadof falling back on the heater to be tossed again they fall into pocketson the descending side of the drum, around which they proceed again forrepetition of the operation just described. 1 have found this motion tobe extremely effective for cleaning bags.

From the foregoing description it will be seen that while theimprovements set forth are simple in character, they will be thoroughlyeffective in securing the object sought, and will combine in thepresentation ofa practical and highly useful machine.

hat is claimed is:

1. A bag cleaning machine comprising a foralninous cylinder including aplurality of peripherally arranged pockets whose inner ends communicatewith the interior of the cylinder, a beater mounted within the cylinder,and connections between the beater and the cylinders for causing them torotate simultaneously in the same direction but at different rates ofspeed.

2. A bag cleaning machine comprisinga foraminous cylinder including aplurality of ends communicate with the interior of the cylinder, a doorclosing the outer end of each pocket, a heater mounted concentricallywithin the cylinder and having the outer 20 extremities of its bladesspaced from the inner ends of said pockets, and connections between thebeater and cylinder for causing them to rotate simultaneously and in thesame direction and the beater at a higher 25 NORMAN E.
